A Mass Spectrograph for Radioactive Isotopes

Abstract
A mass spectrograph for the separation of small quantities of radioactive isotopes is described. This allows a direct determination of the mass numbers of radio‐isotopes. It also permits the determination of the radiation characteristics of each of several radio‐isotopes of an element where these have long half‐lives, or have half‐lives of the same order of magnitude. Slit counter and photographic plate techniques for analysis of deposits are described. An example, the analysis of a rare earth mixture, is described.
